We investigate a methodology for the refinement of finite state machines to time annotated finite state machines. We present a translation, which transforms models into B language code for efficient application of theorem proving. Refinement and verification is performed across three levels with the B-Method and with complementary verification through the RAVEN model checker. The presented methodology...
This chapter describes a case study, which was performed in collaboration of Nokia Research and Paderborn University in the context of the methodology for refinement automation of finite state machines as presentedented in Chapter 10. We elaborate on a combined verification and refinement of an echo cancellation unit of a mobile phone with the Atelier-B toolkit and the RAVEN model checker. The experimental...
